19 Nationwide Values Average Value of Housing Stock - New Zealand Annual and Quarterly Change in Value Nationwide values remain flat according to the latest QV house price index. This nationwide picture is largely influenced by weakening values in Auckland, Hamilton and Tauranga. In much of the rest of the country there has been a slight slowdown in the rate of increase. We continue to expect values to rebound, potentially after the election in September. However the rate of increase in values if and when this rebound occurs will likely be significantly slower than we have seen for the past few years.
